聚氨酯和聚氨酯橡胶是一回事。因为聚氨酯具有良好的回弹性，因此常被称为聚氨酯橡胶，也被称为聚氨酯弹性体。

Polyurethane and polyurethane rubber are the same thing. Because polyurethane has good springback, it is often called polyurethane rubber, also known as polyurethane elastomer.

聚氨酯是由聚酯（或聚醚）与二异睛酸酯类化合物聚合而成的。耐磨性能好、其次是弹性好、硬度高、耐油、耐溶剂。缺点是耐热老化性能差。聚氨酯橡胶在汽车、制鞋、机械工业中的应用最多。

Polyurethane is made from polyesters (or polyether) with two polyesters. Good wear resistance, followed by good elasticity, high hardness, oil resistance, solvent resistance. The disadvantage is that the heat-resistant aging performance is poor. Polyurethane rubber is the most widely used in automobile, shoe making and mechanical industry.

氨酯应该分类成塑料还是橡胶要看实际情况。

Whether the ammonia should be classified into plastic or rubber depends on the actual situation.
